Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an endotracheal tube fixer integrated with a negative pressure suction function. Background Art

[0002] Endotracheal intubation is a technique in which a special endotracheal tube is placed into the trachea through the patient's glottis to assist ventilation. It is widely used in clinical emergency resuscitation, respiratory arrest rescue, surgical anesthesia and airway opening. Clinically, after the endotracheal tube is inserted, in order to avoid the patient's bite causing the endotracheal tube to be closed and to facilitate the fixation of the endotracheal tube, a dental pad is often placed between the upper and lower incisors, and the endotracheal tube and the dental pad are fixed side by side with medical tape. Finally, the dental pad is properly fixed with a fixing belt or tape to prevent the endotracheal tube from slipping and shifting.

[0003] Since patients with indwelling endotracheal tubes usually have more oral secretions, the currently used tooth pads do not have the function of attracting oral secretions. Therefore, nurses are generally required to insert a suction tube into the patient's mouth along the through hole in the middle of the tooth pad to perform suction operations for the patient; a new suction tube must be used each time suction is performed, which increases the expenditure on consumables and the patient's medical expenses. If there are a lot of oral secretions, the nurse needs to frequently perform oral suction, which also increases the workload of nursing. At the same time, the above method cannot perform continuous and uninterrupted suction operations; therefore, a new tooth pad device that can not only fix the endotracheal tube to prevent the patient from biting the tube and the endotracheal tube from slipping and shifting, but also has the function of attracting oral secretions is needed to solve the above problems. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, the utility model patent provides a tracheal tube holder with integrated negative pressure suction function.

[0026] Refer to the instruction manual Figure 1-5 A tracheal intubation holder with integrated negative pressure suction function comprises a tooth pad body 1, a wing plate 2, a fixing part 3 and a negative pressure suction component. The tooth pad body 1 is a columnar structure made of hard plastic, and a tongue depressor is extended from the lower front end of the tooth pad body 1 along its length direction, so that the front end of the tooth pad body 1 forms a wedge-like structure. The two wing plates 2 are respectively vertically and fixedly installed on the middle of the top and bottom surfaces of the tooth pad body 1. The wing plate 2 is an arc-shaped structure. When in use, the tooth pad body 1 is placed between the upper and lower incisors, and the wing plate 2 rests against the patient's lips.

[0027] Refer to the instruction manual Figure 1-4 The negative pressure suction component includes a connecting tube 4, a suction tube 5 and a negative pressure connector 6. The connecting tube 4 is arranged inside the dental pad body 1, one end of which is connected to the suction tube 5 arranged at the front end of the dental pad body 1, and the other end extends out of the rear end of the dental pad body 1 and is connected to the negative pressure connector 6. The negative pressure connector 6 is used to connect a negative pressure suction device. The negative pressure suction device can use a syringe to achieve intermittent sputum suction, or the negative pressure suction device is composed of a pressure regulator, a liquid collecting bottle, a hose, a negative pressure terminal, etc. There are two hose interfaces on the liquid collecting bottle, one is connected to the negative pressure terminal, and the other is connected to the negative pressure connector 6. When the negative pressure terminal is connected, negative air pressure will be generated in the liquid collecting bottle. The negative pressure will guide the sputum to flow into the liquid collecting bottle from the suction tube 5, the connecting tube 4, the negative pressure connector 6, and another hose in sequence. The pressure regulator is used to adjust the negative pressure to achieve continuous sputum suction.

[0028] Refer to the instruction manual Figure 1 , 2 A suction tube 5 is provided, and the suction tube 5 is arranged at the front end of the tooth pad main body 1, and the suction tube 5 is connected with the connecting tube 4; at the same time, the suction tube 5 and the connecting tube 4 can be the same pipe, the middle part of the pipe is arranged in the tooth pad main body 1, the front end of the pipe extends out of the front end of the tooth pad main body 1 to form the suction tube 5, and the rear end of the pipe extends out of the rear end of the tooth pad main body 1 and is connected with the negative pressure joint 6, that is, the connecting tube 4 is arranged in the tooth pad main body 1, and the rear end of the connecting tube 4 extends out of the rear end of the tooth pad main body 1 and is connected with the negative pressure joint 6.

[0029] In a preferred embodiment, in order to perform negative pressure suction on sputum at multiple positions in the oral cavity, three suction tubes 5 are provided, and the three suction tubes 5 are provided at the front end of the tooth pad body 1, and are spaced apart in the left, middle and right directions of the front end of the tooth pad body 1 (specifically corresponding to suction of sputum on the left, upper and right sides of the patient's tongue);

[0030] The front section of the connecting tube 4 is in the tooth pad body 1, and the rear section extends out of the rear end of the tooth pad body 1 and is connected to the negative pressure joint 6. The rear ends of the three suction tubes 5 enter the tooth pad body 1 and are respectively connected to the connecting tube 4 or multiple suction tubes 5 are connected to each other and then connected to the connecting tube 4. The connection method of the three suction tubes 5 and the connecting tube 4 is similar to the one-to-three form, that is, one end of a connecting tube 4 branches into three suction tubes 5.

[0031] Refer to the instruction manual Figure 7 The end of the suction tube 5 is an arc-shaped end, which can prevent the end of the suction tube 5 from damaging the oral mucosa. A plurality of suction holes 51 are provided on the suction tube 5. The plurality of suction holes 51 are evenly arranged along the axial direction and / or circumferential direction of the suction tube 5, which can facilitate the suction of sputum in multiple positions and directions.

[0032] Refer to the instruction manual Figure 6The negative pressure joint 6 is a pagoda joint, which includes a plurality of conical clamping parts arranged in a stepped manner, and the taper of the plurality of conical clamping parts gradually increases from the outside to the inside. A sealing cover 8 is connected to the negative pressure joint 6 through a connecting belt 9. The sealing cover 8 is used to seal the end of the negative pressure joint 6. The pagoda joint is convenient for connecting pipes of different specifications to improve applicability. At the same time, the sealing cover 8 can seal the end of the negative pressure joint 6 to prevent the end of the negative pressure joint 6 from being directly exposed and contaminated during intermittent sputum suction.

[0033] Refer to the instruction manual Figure 1 , 2 A through hole 11 is provided along the length direction of the tooth pad body 1. The through hole 11 is convenient for observing the suction of sputum in the oral cavity and for using an external suction device to extend through the through hole 11 to perform auxiliary suction of sputum in the oral cavity or deep in the oral cavity.

[0034] The inventors also found that currently, medical tape is generally used to fix the endotracheal tube and the bite block side by side. The oral secretions of patients with endotracheal tubes are usually more, which can easily make the medical tape wet and lose its stickiness, resulting in a weakened fixing effect, which may cause the endotracheal tube to slip and shift. Therefore, a fixing member 3 for fixing the endotracheal tube is fixedly installed on the side of the bite block body 1;

[0035] Refer to the instruction manual Figure 1-5 The fixing part 3 includes an annular elastic buckle arranged side by side with the tooth pad body 1. The annular elastic buckle is arranged at a position between the front end of the tooth pad body 1 and the wing plate 2. The length of the annular elastic buckle is less than or equal to the horizontal distance between the front end surface of the tooth pad body 1 and the wing plate 2, so that the annular elastic buckle is in the area outside the patient's oral cavity, which is convenient for the nurse to operate; the annular elastic buckle is fixedly installed on the side of the tooth pad body 1, and a clamping cavity 32 is formed inside the annular elastic buckle. The inner diameter of the clamping cavity 32 is smaller than the outer diameter of the endotracheal tube, and an opening 31 connected to the clamping cavity 32 is opened on the side of the annular elastic buckle facing away from the tooth pad body 1.

[0036] The endotracheal tube can be pressed into the clamping cavity 32 through the opening 31, and the endotracheal tube can be fixed by the elastic force of the annular elastic buckle. At the same time, a rubber layer or anti-slip bumps can be provided on the inner wall of the clamping cavity 32 to increase friction.

[0037] After the endotracheal tube and the bite block body 1 are fixed side by side, in order to prevent the patient from swallowing or spitting out the bite block body 1 by mistake, and to prevent the endotracheal tube from slipping and shifting, it is necessary to fix the position of the bite block body 1 and the endotracheal tube; refer to the attached manual Figure 1 , 2 , 3, 5, a fixing hole 21 is opened on the upper wing plate 2, and the fixing hole 21 is located in the middle of the wing plate 2. A fixing belt (omitted in the drawings) is connected to the fixing hole 21, and the fixing belt is used to wrap around the head or neck for fixing;

[0038] Specifically, the fixing belt can be a whole cloth belt with a certain width, and Velcro that can be adhered to each other is respectively provided at both ends of the cloth belt. The cloth belt passes through the fixing hole 21, and the middle section of the cloth belt is located at the fixing hole 21. The cloth belt is knotted and fixed at the fixing hole 21, and the two ends of the cloth belt are respectively wrapped around the back of the head or neck and then adhered and fixed or knotted by Velcro. The fixing belt can also be two cloth belts with a certain width, one end of the two cloth belts is knotted and fixed on the fixing hole 21, and the other ends are respectively provided with Velcro that can be adhered to each other, and the other ends of the two cloth belts are wrapped around the back of the head or neck and then adhered and fixed or knotted by Velcro.

[0039] Since the main body 1 of the dental pad is made of hard plastic, the patient's teeth bite directly on the main body 1 of the dental pad, and the patient's lips directly contact the main body 1 of the dental pad and the wing plate 2, which is easy to damage the oral mucosa and lips. Especially for the elderly, long-term occlusion can easily make the teeth loose. Therefore, refer to the attached manual Figure 1-4 A flexible cushion layer 7 is fixedly provided on the top and bottom surfaces of the tooth pad body 1 at the rear end of the wing plate 2. The flexible cushion layer 7 and the wing plate 2 are made of soft elastic rubber or soft elastic plastic or silica gel or polyethylene vinyl acetate;

[0040] After the tooth pad body 1 is placed between the upper and lower incisors and the wing plate 2 rests against the patient's lips, the patient's teeth bite on the flexible pad 7, and the lips are also in contact with the flexible pad 7 or the soft wing plate 2, which can prevent damage to the oral mucosa and lips and loosening of the teeth to a certain extent.

[0041] The method of using the endotracheal tube holder with integrated negative pressure suction function in this embodiment is as follows: after the endotracheal tube is indwelled in the patient, the bite block body 1 is placed between the upper and lower incisors, the wing plate 2 is pressed against the patient's lips, and the endotracheal tube is pressed into the clamping cavity 32 through the opening 31 to achieve a fixed connection between the endotracheal tube and the bite block body 1, a fixing belt is passed through the fixing hole 21, and the middle section of the cloth belt is located at the fixing hole 21. After the cloth belt is tied and fixed at the fixing hole 21, the two ends of the fixing belt are respectively wrapped around the back of the head or neck and then passed through the fixing hole 21. The endotracheal tube is fixed to the dental pad body 1 by adhesion or knotting with Velcro, and finally, the negative pressure connector 6 is connected by a syringe or other instrument to perform regular intermittent sputum suction. After one sputum suction operation is completed, the syringe or other instrument is removed and the end of the negative pressure connector 6 is sealed with a sealing cover 8, or the negative pressure connector 6 is connected by a negative pressure suction device to perform continuous sputum suction. At the same time, the sputum suction in the oral cavity can be observed through the through hole 11 during the retention of the endotracheal tube, and an external suction device can be used to perform auxiliary sputum suction in the oral cavity or deep in the oral cavity.

[0042] Obviously, it is possible to modify and / or add components to the above-mentioned endotracheal tube holder integrated with negative pressure suction function and the corresponding method without departing from the field and scope of the present invention.

[0043] It is also clear that although the utility model has described the endotracheal tube holder with integrated negative pressure suction function in detail, technicians in this field will certainly be able to obtain many other equivalent forms of endotracheal tube holders with integrated negative pressure suction function and corresponding methods. The endotracheal tube holder with integrated negative pressure suction function and the corresponding method have the characteristics described in the claims, and therefore are all within the scope of the protection field defined thereby.
